- Аннотация: MASTER Global robotic net (http://observ.pereplet.ru Lipunov et al.,2010,Advances in Astronomy,2010,30L) started EP 240416A (Cheng et al. #GCN 36138, Triggertime= 2024-04-16 02:42:13UT, Notice=2024-04-16T16:41:11, Center R.A.,Dec. = 203.150 -13.612) optical (unfiltered) observation at 3 MASTER observatories. MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to EP240416A error-box 66152 sec after trigger time at 2024-04-16 21:04:45 UT, with upper limit up to 19.4 mag. The observations began at zenith distance = 56 deg. The sun altitude is -36.6 deg. MASTER-Tavrida robotic telescope located in Russia was pointed to the EP errorbox 66334 sec after trigger time at 2024-04-16 21:07:47 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 57 deg. The sun altitude is -35.0 deg. MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) was pointed to the EP Alert 240416.11 errorbox 67795 sec after trigger time at 2024-04-16 21:32:08 UT, with upper limit up to 20.0 mag. The observations began at zenith distance = 22 deg. The sun altitude is -63.6 deg. The galactic latitude b = 48 deg., longitude l = 319 deg. There is no OT (Chen et al. #GCN 36139) in MASTER database since 2003y, that can confirm Kinder optical afterglow. Observation and analysis will be continued. We obtained the following upper limits.
